You will hear the term a lot in business rules, shipping estimates, bank processing, and deadlines. For example, if a company says something will arrive in five business days, that usually means you don’t count Saturday or Sunday, only the normal workdays.
Typical Hours in a Business Day
In many countries, especially in the United States, the UK, and many European nations, a business day usually lasts about 8 hours, most commonly from 9:00 a.m. to 5:00 p.m.
This 9–5 schedule is often called “standard business hours.” In this time, banks, offices, and many companies are open and doing work. Some firms may start earlier (like 8:00 a.m.) or finish later (like 6:00 p.m.), but the idea is similar: the day is long enough for regular business work.
However, business hours and business days are not the same—business days refer to the full day, while business hours are the time in that day when people work. A business day may include breaks, lunchtime, or overtime, but many agreements count the whole day, not exact hours.
How Many Hours Are in One Business Day?
Most people think a business day has about 8 hours of work time. That is the common idea in many companies and banks.
Example:
If a store opens at 9:00 a.m. and closes at 5:00 p.m., that is 8 hours. Many office workers follow this schedule. However, this can change:
- Some businesses start at 8:00 a.m. and end at 4:00 p.m.
- Some close at 6:00 p.m. or run six‑day workweeks in certain countries or industries.
Because of this, “business day length” is not exact worldwide, and it depends on the business, region, and type of work.
How Long Is a Business Week?
A business week is usually five business days—from Monday to Friday. Most jobs and companies follow this pattern.
In some countries, the workweek can be Sunday through Thursday, so those days become the business days. Other places may count Saturday as a working day for some jobs, but most official business and legal processes still use the five‑day week for deadlines and scheduling.
Business Day vs. Calendar Day
A calendar day is any day—Monday through Sunday—including weekends and holidays. A business day only counts the days businesses normally work.
Example: If you order something on Thursday and the seller says it will take 2 business days, you count:
- Friday (Day 1)
- Monday (Day 2)
Because Saturday and Sunday are weekends, they are not business days, even though they are calendar days.
This difference is important when calculating delivery times, bank processing times, and legal deadlines.
How Holidays Affect a Business Day
Public holidays—like New Year’s Day, Christmas, or other national holidays—are usually not counted as business days. So if a deadline is in “5 business days” and one of those days is a holiday, you add one more calendar day.
For example, if a holiday falls on Wednesday, and you count business days from Monday, you would skip that Wednesday in your count, and your final deadline would be pushed one day later in the calendar.
Variations Around the World
Business days and working hours can be different in other countries:
- In the Middle East, the business week may run from Sunday to Thursday.
- Some countries have longer business hours or include Saturday as a business day in certain industries.
- In sectors like retail, healthcare, or 24/7 service industries, businesses may be open every day, but for purposes like shipping or legal calculations, the traditional business days usually still follow Monday to Friday.
Because of these differences, it’s always a good idea to clarify what “business days” means when you agree on deadlines or schedules—especially internationally.
Why Understanding Business Days Matters
Understanding how long a business day is helps you know:
✔ When to expect deliveries or services
✔ How long bank transactions may take
✔ When deadlines are due in contracts
✔ How long processing times will be for loans, returns, or customer support
For businesses, it helps with planning meetings, scheduling work, and keeping customers informed. For customers, it prevents confusion about when to expect responses or products.
